The obvious solution is to let the trip take 100,000 years and the population rides as test tube embryos to be grown and raised by machines after they...
I don't buy this. By this logic, If there is a test to communicate with a squirrel and convince the squirrel that the entity at the other end of the t...
Not in any long run, no. Small differences are amplified, not lost in the averages. Get familiar with chaos theory, or what is popularly known as the ...
I watched it enough to see that it was the same thing as the sites that come up with the same search. What they are calling dimensions is not the geom...
Having a hard time parsing this statement. The only way that makes sense is if you're saying that such concepts are important for a rational thinker, ...
Buy it for 2 cents, and one of the wishes is to produce a buyer at a penny. This exercise seems chock full of loopholes. Another way is to set up a Hi...
Your choice of QM interpretation most definitely go with certain philosophical stances and not others. It seems important to be compatible. But I agre...
You make it sound like speed is a property of an object. It isn't. I am not moving at some speed. I can only have speed relative to an arbitrary refer...
The primary one is the philosophical interpretations of time: presentism and eternalism. The former was always the default until relativity gave equal...
SR says that local experiments would not be able to detect the speed, meaning no differences. Looking out of the window constitutes a non-.local test,...
Yes. With locality, which is essentially saying no FTL. Pilot wave is a form of Bohmian mechanics: Pro counterfactual definiteness (objective state) a...
Obviously yes, your topic being a prime example. I choose to interpret it otherwise. Yet that is exactly how mathematical progress was always made. No...
This is why I resist describing RQM under presentist terms. If time is external to the structure that is the universe, then such selection is an objec...
The Andromeda Paradox is about the ambiguity of what time it is elsewhere, not about the state being definite. The former is a frame dependent thing a...
I consider it something discovered, not invented. If invented, pi would not be the same value in another world. OK, odds are the aliens don't express ...
I thought about that and it seems that post-measurement Alice has the same relationship to pre-measurement Alice as the relationship to post-measureme...
Exactly so. That's why it is called the theory of relativity and not the theory of objectivity. It's only a problem if you add that additional premise...
My comments pretty much reflect the Everett interpretation, and not DeWitt's. Both are grouped under the same heading in the wiki list, but you point ...
The worlds are not really separate under MWI. There is but the one wave function and the various solutions to the wave function. Excerpts from https:/...
I should reword. Yes, the odds are almost a certainty from the beginning that the unicorn will occur in some world, but I meant given a single measure...
For all those Alices (Alici? :confused:) to exist, you need to change the definition of 'exist' from the RQM one to the MWI one. The change of definit...
We are starting to agree more and more, making these posts a bit shorter. Well, I was presuming their possibility. It's just a horse-like thing with a...
Well good. Being sure is being closed minded. I try not to be sure about anything, but I do it anyway. The table lamp does acquire information (physic...
Apologies for slow reply time. A tool (a map of Paris say) may be just a tool and not be the thing it describes, but it very much still describes Pari...
I have a rough time with this distinction. Something not real can still be used to describe a real thing. It just isn't the actual thing. I think more...
There is certainly no one version of probably any of the interpretations, but there are probably some fundamental features that characterize each. Tak...
Such an interpretation would seem to propose counterfactual definiteness. Somewhere off to the side, some measurement is taken by not-me and causes so...
I think we observe it every day, but you take it as an ordinary observation. A rainbow is quite impossible to see without superposition. The lens of m...
RQM indeed does not claim anything about what path is taken. Any statement about the path taken (such as it taking one or the other) would be a counte...
That seems to work. I considered myself in relation to that alien who came from far away and has yet to observe what's here. To that alien, I am very ...
The interferometer seems to be the only measurement taken (the only observer). Anything outside that is only noting what was measured by that device. ...
My comment is applicable to your reply. Wigner's friend is is superposition in relation to Wigner. The friend measuring himself sees no such thing and...
It makes perfect sense. The photon cannot take one path, unmeasured. That would be the counterfactual definiteness that any local interpretation denie...
Suppose you wanted to measure the diameter of a pizza. The way to do that is to put the pizza in front of you and hold a tape measure up to it, but th...
The article says that an external system can take this more 'full measurement' of some system, but not any system containing the system being measured...
I think this was addressed to me. An observer occupies all reference frames, but is stationary in only one of them. Without an actual observer doing a...
Hard to understand is my current state of affairs. I don't get a clear statement about how it differs from the others. The man on the street, sure, bu...
From some (most) perspectives, there is no 'it' to be an electron. To consider an electron is to have already assumed a perspective where it exists. I...
I have a hard time keeping up with you guys :) This isn't the QM I know. There is no 'big difference' between the two cases. The cat is both dead and ...
OK, that's what you meant by the self reference issue. Theorem aside, it seems quite intuitive that an aparatus cannot measure all of its own states s...
Not the way Rovelli is defining the word. I personally dislike such usage because it encourages exactly such misinterpretations. It is warmer than the...
He's not saying that the lamp is taking note of the hand motion. He's just saying that the motion is relative to the motion of the lamp, be it noticed...
Sort of. Tegmark takes the MWI position that the structure (the universal wave function) exists, and thus he has to explain its 'being'. I don't buy i...
That sounds like a reference frame, which A) doesn't require an object stationary in that frame to define it, and B) has nothing to do with what cause...
Don't think there is such a cut with Wigner's interpretation. Consciousness causes collapse, period. If the cat is conscious, then it can't be in supe...
It is meaningful to say that there are individual systems like S? That sounds an awful lot like counterfactual definiteness. A system with states stil...
Existential nihilism perhaps. Life still has meaning, even if that meaning isn't objective. Even a typical theist doesn't really consider say morality...
With this I agree. I often characterize it the way Bohr did: as a description of what can be known, and not at all a description of what is. It is rat...
OK, my comment assumed it was an interpretation. But if the the different theory is experimentally differentiable from standard QM, then by all means ...
